Abstract: A first computing device may comprise at least one audio output and at least one audio input. The first computing device may determine a first delay associated with output of first audio from a second computing device located remote to the first computing device. Output of second audio may be caused via the at least one audio output based on the first delay. An audio input signal comprising the first audio, the second audio, and third audio indicative of a voice command may be received via the at least one audio input. At least one action may be caused to be performed based on the voice command. The at least one action may be caused to be performed based on removal of the first audio and the second audio from the audio input signal.

Abstract: One or more portions of audio input may be detected. One or more directions associated with the one or more portions of audio input may be determined. A difference in direction between the one or more directions may be determined. An end of speech may be determined based on the difference in direction. An action may be taken based on the end of speech.

Abstract: Systems, apparatuses, and methods are described for determining a direction associated with a detected spoken keyword, forming an acoustic beam in the determined direction, and listening for subsequent speech using the acoustic beam in the determined direction.

Abstract: Methods and systems for audio interference cancellation are disclosed. A first beamforming zone associated with a location of a first audio source may be determined. A second beamforming zone associated with a location of a second audio source may be determined. Based on determining that first audio associated with the first audio source dominates a first frequency band associated with the first beamforming zone and the second beamforming zone, prevention of attenuation of audio output in the first beamforming zone and within the first frequency band may be caused. Based on determining that second audio associated with the second audio source dominates a second frequency band associated with the first beamforming zone and the second beamforming zone, attenuation of audio output in the first beamforming zone and within the second frequency band may be caused.

Abstract: Systems, methods, and devices relating to audio correction are described. A first portion of content including first spoken audio content indicating first word(s) may be determined. Background audio content of the first portion of the content may be determined. A voice profile may be determined based on the first spoken audio content. Based on the voice profile, second spoken audio content indicating second word(s) to replace the first word(s) may be generated. Based on mixing the background audio content and the second spoken audio content, a second portion of content may be determined. In the content, the first portion of the content may be replaced with the generated second portion of content.

Abstract: Systems, apparatuses, and methods are described for determining a direction associated with a detected spoken keyword, forming an acoustic beam in the determined direction, and listening for subsequent speech using the acoustic beam in the determined direction.

Abstract: Systems, apparatuses, and methods are described for keyword detection. A first detector device may receive audio and process the audio to determine a confidence value regarding presence of a keyword. A copy of the audio may be passed to a second detector device to perform additional testing for the audio. The first detector device may take an action before or after sending to the second detector device based on the confidence value.

Abstract: An apparatus and methods for a wireless telecommunication system to provide a wireless interface. A plurality of modems is used for processing wireless communications with a plurality of subscriber line circuits, each for providing a telecommunication connection. A control processor assigns a modem for each communication, selects one of the line circuits and associates that line circuit with the assigned modem for that communication. Thus, any of the line circuits can be used to communicate via any of the modems.

Abstract: Voiceband compression techniques are employed in order to enable an RF telecommunications base station to accommodate data signals of high speed voiceband modems and FAX machines. An Ultra-High Speed Codec supports voiceband modem and FAX transmissions up to 14.4 kb/s and operates using four 16-phase RF slots. Because these codecs transmit information over several RF slots which can be contiguous, the slots within RF communication channels are dynamically allocated. The Dynamic Time slot/Bandwidth Allocation feature detects and monitors the data transmission and forms a data channel from the necessary number of slots.
